The shiny rate increased from 1/8192 to 1/2048 (although it seems to be even higher than this!).Most notably Ice type is now immune to ice and resists water/ ground attacks

The type chart has been edited a little to help balance the game.

In addition, any evolutions will be possible without having to trade. If a Pokémon has an evolution/pre-evolution introduced in gen 3/4 it’ll be available pre-league and all evo items can be obtained in new ways. For example, Rock smash has increased pp and 100% chance to lower defense and Flash is now an electric type special move with 20 power, 95 accuracies, 100% chance of lower accuracy, and has priority. Notably, HMs are now actually better in battle so they don’t hinder your Pokémon as much.

Some moves have been edited to be more usable.

These changes aren’t as drastic as other hacks like Project rebooted. Examples include Dragon-Bug Yanmega, Beedrill having slightly higher stats, and learning Megahorn at later levels.

Some Pokémon have slightly altered stats, typing, and movesets in order to make them more usable, to add more type variety, or just because it makes sense.

All Pokémon have their base stats updated to their Gen 6 stats.

The Hack should work on flashcards like the R4!.

This means Kanto should be more of a challenge now! The difficulty is intended to be somewhere in between vanilla SoulSilver and StormSilver. Starting from the 4th gym all trainers will have increased levels. All boss trainers have improved teams with better movesets and Remember back in the original SoulSilver when you would find a trainer with 5 Pidgeys or when you fought Lance and he had 3 Dragonites? That won’t happen anymore, trainers will have more varied teams and Pokémon that didn’t appear much previously will do now.

Gold/ Kris will now act like a rival with new dialogue and a few battles throughout the game!.

All gen 1 & 2 Pokémon (apart from legendaries and fossil pokémon) are available before beating the league, and most gen 3 & 4 pokémon aside from the Sinnoh fossils, Spiritomb, and some legendaries.

This is an improvement-type hack with many quality of life changes and increased difficulty. Also, be sure to check out Pokemon Black 2 Extreme Randomizer Description
